Interesting article on how Apple can update even its latest software
model to fix security bugs. it is this aspect which the USG is
challenging and wants Apple to use to disable the "no more than 10 times
the wrong password, else the data will be destroyed" feature and allow
it to be able to get into the phone using brute force techniques which
will not destroy the data on the phone.
